Chemical Profiling and Bioactivity of Body Wall Lipids from Strongylocentrotus droebachiensis
The lipids from gonads and polyhydroxynaphthoquinone pigments from body walls of sea urchins are intensively studied. However, little is known about the body wall (BW) lipids. Ethanol extract (55 °C) contained about equal amounts of saturated (SaFA) and monounsaturated fatty acids (MUFA) representing 60% of total fatty acids, with myristic, palmitic and eicosenoic acids as major SaFAs and MUFAs...

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولDynein-like Mg"-ATPase in Mitotic Spindles Isolated from Sea Urchin Embryos (Strongylocentrotus droebachiensis)
Two distinctly different ATPases have been reported to be endogenous to the mitotic apparatus: a Mg2+-ATPase resembling axonemal dynein, and a Cat+ -ATPase postulated to be bound in membranes. To examine the nature of the Mgt+-ATPase, we isolated membranefree mitotic spindles from Strongylocentrotus droebachiensis embryos by rapidly lysing them in a calcium-chelating, low-ionic-strength buffer ...

متن کاملPopulation Dynamics and Spatial Analysis of the Maine Green Sea Urchin (strongylocentrotus Droebachiensis) Fishery By
Fisheries research on the green sea urchin in Maine has been limited despite its importance to the state's fishing industry. The objective of this thesis was to generate critical information for the management and monitoring of the Maine green sea urchin fishery. In particular there are three main areas of interest: (1) an investigation of biological reference points; (2) spatial analysis and b...
